FIG. 1 is a flowchart illustrating a method of transmitting a message according to an embodiment. According to an embodiment, the method of transmitting a message, hereinafter simply referred to as a message transmitting method, may add a game element to a general message transmitting method to transmit a message by throwing a message box towards a receiver based on a message transmission command input from a user, as if playing a shooting game. The message box is an item embodying a transmission medium including a message, for example, a carrier pigeon, an airplane, a missile, and a mailbox, or may include, for example, a letter paper and a letter envelope including message contents.

FIG. 2 is a diagram illustrating a message box according to an embodiment. Referring to FIG. 2, the message box is determined as one of a carrier pigeon 210, an airplane 220, and a missile 230, and each may have a mass value and an air resistance value. The mass and air resistance values are used to embody a message box moving or flying to a receiver in operation S130. Although the mass and air resistance values are indicated as an attribute of the message box, the message box may have various attributes, for example, a volume, a density, and a material quality. The message box may be determined based on a marker, selected by a user, or determined based on a distance between the user and the receiver. For example, the airplane 220 may be determined as the message box for a short distance, the carrier pigeon 210 for a middle distance, and the missile 230 for a long distance.

The message transmitting method will be described in detail hereinafter with reference back to FIG. 1. In operation S110, the user obtains a surrounding image using a camera embedded in a user terminal of the user. The message transmitting method may improve a sense of reality and interest in a message transmitting game using augmented reality technology. Such augmented reality technology may be used to embody an image appearing as if a user transmits a message by throwing a message box directly to a receiver in a real world.

In operation S120, the user terminal receives a transmission command of a message, which is a command for transmitting a message, as an input from the user. The user terminal may specify the receiver by receiving a preregistered name, phone number, mail address, and the like from the user, or by performing facial recognition on the obtained image. The transmission command may be input from the user pressing or touching a button corresponding to a command, for example, “transmit,” “launch,” “start,” or “send.” Alternatively, the transmission command may be input from the user performing a shooting gesture. The shooting gesture may be a motion input for commanding transmission of a message, and may be input through a user interface. The user terminal may receive an attribute value of the transmission command from the user. The attribute value of the transmission command may be associated with transmission of the message box, and may be received as a value of a moving direction, a moving speed, a moving distance, a movement time, and the like of the message box from the user, or be calculated based on a direction, a distance, a speed, a displacement, a time, and the like of the shooting gesture.

The shooting gesture may be a hand gesture to be input through a touch sensor of the user terminal or a motion sensor of the user terminal configured to sense or detect a movement occurring in the vicinity of the user terminal. In such a case, the shooting gesture may be converted to data including at least one set of information about a moving direction, a moving distance, a speed, a displacement, and a time of the hand gesture. For example, the user terminal may receive, as an example of the shooting gesture, a gesture of pulling the message box displayed on a touch display and then putting the message box, which is performed by the user, through a touch panel. For another example, the user terminal may receive the shooting gesture by detecting a movement of a finger in an image input through the camera, or by detecting a change in an air pressure by a movement of a finger through a microphone.

According to another example, the shooting gesture may be a movement of the user terminal to be input through the motion sensor of the user terminal. In such a case, the shooting gesture may be converted to data including at least one set of information about a moving direction, a moving distance, a speed, a displacement, and a time of the user terminal. For example, when the user performs a gesture of grabbing the user terminal and then throwing the user terminal, data such as moving direction data, moving distance data, speed data, displacement data, or time data of the user terminal may be obtained by measuring a speed, a direction, an angle, a distance, and the like of the user terminal through a gravity sensor, a geomagnetic sensor, an acceleration sensor, and a gyrosensor embedded in the user terminal.

The attribute value of the transmission command may be used to embody an augmented reality image of the moving message box in a subsequent operation.

In operation S130, the user terminal applies the message box moving to the receiver based on the transmission command based on the augmented reality technology, and outputs the image to which the message box is applied. A detailed method of outputting the message box onto a screen will be described with reference to FIG. 3.

In operation S140, the user terminal transmits the message to the receiver. According to an embodiment, only when the transmission command adjusted to allow the message box to directly hit the receiver is input, the user terminal may transmit the message to the receiver. When the message box does not directly hit the receiver, the transmission command may be continuously input until the message box directly hits the receiver. Alternatively, when the transmission command is input, the message box being transmitted may be displayed on the screen irrespective of whether the message box directly hits the receiver, and the message may be transmitted to the receiver.

In operation S150, when the message arrives at the receiver, the user terminal applies the message box directly hitting the receiver to the obtained image, and output the image to which the message box is applied. For example, a missile being exploded or a pigeon setting off fireworks while hovering around the receiver may be displayed on the obtained image by being augmented.

The message box may be augmented in a captured image based on a marker or markerless. For example, in a marker-based method, a message box suitable for a type of a marker to be detected in the captured image may be embodied and augmented on the screen, and the message box may fly emitting a flame and smoke when the transmission command is input from the user.

FIG. 3 is a flowchart illustrating a method of augmenting a moving message box on a screen according to an example embodiment. A method of embodying a moving message box by a user terminal will be described hereinafter. In operation S132, the user terminal determines a trajectory based on a location of a receiver, an attribute of the message box, an attribute of a transmission command of a message, and the like. For example, the user terminal may determine the trajectory based on a mass and an air resistance of a selected message box, and a direction and a speed of a shooting gesture. For another example, the user terminal may determine the trajectory by setting the location of the receiver to be a destination of the trajectory, and setting the direction and the speed of the shooting gesture to be an initial setting value. For example, the user terminal may determine the trajectory according to technology disclosed in Korean Patent Publication No. 10-2011-0121835 (entitled “game terminal for using a camera and operating method for the same”). When the receiver is included in an obtained image, the user terminal may detect the location of the receiver from the obtained image. Conversely, when the receiver is not included in the obtained image, the user terminal may detect the location of the receiver based on global positioning system (GPS) information of a terminal of the receiver.

FIGS. 4 and 5 are diagrams illustrating examples of a trajectory along which a message box moves. FIG. 4 is a diagram illustrating an example of a trajectory along which a message box moves when a receiver is included in an obtained image according to an example embodiment. Although a user terminal may detect a location 410 a of a receiver using GPS information of a receiving-end terminal when the receiving-end terminal is specified, detecting a location 410 b of the receiver by analyzing an obtained image may enable a higher accuracy in embodying augmented reality. When a user performs, as a shooting gesture, a gesture of grabbing a missile 430 displayed on a touch display and then putting the missile 430, the user terminal may determine a trajectory 420 from the user terminal to a detected location of the receiver. FIG. 5 is a diagram illustrating an example of a trajectory of a message box to transmit a message to a remotely located receiver according to another example embodiment. In the example of FIG. 5, a user located in Yeoksam-dong arranges a user terminal towards Nonhyeon-dong and inputs a shooting gesture to transmit a message to a receiver located in Banpo-dong. Here, the user terminal may receive information of the receiver from the user, and detect a location of the receiver using GPS information of a receiving-end terminal. When the location of the receiver is determined, the user terminal may determine a trajectory 520 by determining an initial trajectory value based on the shooting gesture and setting the location of the receiver as a destination.

Referring back to FIG. 3, in operation S134, when the trajectory is determined, the user terminal renders, on the captured image, the message box moving to the receiver along the trajectory. For example, based on the trajectory, for example, the trajectory 420 and the trajectory 520 of FIGS. 4 and 5, respectively, an image of a message box flying as illustrated in, for example, 440 of FIG. 4 and 530 of FIG. 5, may be augmented in an image obtained using a camera and the augmented image may be displayed on a screen.

FIG. 6 is a diagram illustrating a flow of a method of selling a message box according to an example embodiment. According to an example embodiment, a new business model of selling a message box is provided based on the message transmitting method described with reference to FIG. 1.

In operation S610, a selling server receives a request for sales information of at least one message box from a user terminal. Here, the message box is an item embodying a message transmission medium, and is displayed on a screen of the user terminal as an augmented reality-based virtual object. In operation S620, the selling server reads out sales information of at least one preregistered message box. For example, the message box may be prestored or preregistered in the selling server, after developed by a message transmission service provider or a third party desiring to sell the message box. In operation S630, the selling server transmits, to the user terminal, the read sales information of the at least one message box. In operation S640, the user terminal receiving the sales information of the at least one message box outputs the sales information to allow a user to select a desired message box. In operation S650, the user terminal requests purchase of the selected message box. In operation S660, when the request for the purchase of the message box is input from the user terminal, the selling server performs a billing process for the message box for which the request for the purchase is made. In operation S670, the selling server transmits, to the user terminal, the message box for which the billing process is completed to allow the user to use the message box. The selling server may operate in a single computer, or operate in a plurality of computers operating based on each function.
